如何从电子表格中的特定单元格调用Python脚本

Question

I have a Python script to interact with a database and give some result. I create a new sheet in a workbook and save this result.

I have a workbook and I want to call this script from all the cells in a particular row in the active sheet of the workbook using the cell value as an argument to the script.

I came to know the following things
1) Create a VBA macro and call a script from the macro
2) Insert the macro in the sheet

I have zero knowledge about VBA and was not able to find good resources for it.

Can my problem can be solved using Python itself?

Can I call a Python script from some cells in a workbook using cell values as an argument to the script?

Answer 1

Your question is too broad. The answer is yes. There are several libraries for it. Look into openpyxl , win32com : also called pywin32 , and pandas

Of these 3,
openpyxl is the easiest to use but might not contain the full functionality of Excel VBA.
win32com is the closest to VBA and most function calls are the same right down to the way arguments are passed into them.
pandas is the right choice if you're crunching a lot of numbers and mainly using the spreadsheet files as data storage.

EDIT:

VBA Code:

Public Sub StartExeWithArguments()
    Dim wb As Workbook
    Set wb = ThisWorkbook
    Dim ws As Worksheet
    Set ws = wb.Sheets("Config") 'Have a sheet named "Config"

    'The values here are for passing in the args to a python script that runs as an .exe file
    strProgramName = Trim(ws.Range("B4").Value) '.exe filepath
    strPdfLoc = Trim(ws.Range("B5").Value) 'file being acted on
    strPdfSave = Trim(ws.Range("B6").Value) 'file being created
    strPdfPass = Trim(ws.Range("B7").Value) 'additional argument
    'string concatenation
    strArgument = strPdfLoc & " " & strPdfSave & " " & strPdfPass

    'Checking the cmd line to be passed into the Shell as args for the .exe
    Debug.Print """" & strProgramName & """ " & strArgument & """"
    'How VBA calls the cmd to run
    'Note that """" actually prints one " because " is an escape char and also a string quote in VBA
    Call Shell("""" & strProgramName & """ " & strArgument & """", vbNormalFocus)
End Sub

The above code showcases how you can create a macro to run an .exe and pass in arguments.
As for trigger on cell selection , use the example showcased in this link .

In order to create an .exe file, use pip3 install pyinstaller and cd your way to the folder containing the .py script, then run pyinstaller --onefile yourscript.py
